In this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (PVA) and N,N'-dimethyl formamide (DMF). The Characterization of the samples were carried out using X-ray diffraction (XRD), Transmission-electron microscopy (TEM) and UV-vis spectroscopy. Absorption spectra of the nanoplates in comparison with that of the silver spherical silver NPs proved a quite different feature due to the silver nanoparticle anisotropic shape. It may be due to the specific interaction between OH groups and Ag+ ions, which affect the selective growth of various planes of silver nanocrystals.
